Wireless earbud

Abstract

An earbud includes a housing having a main body portion having a speaker port and a stoke extending from the main body portion; a radiator disposed in the stoke to radiate radio signals to the outside of the earbud; and a printed circuit board (PCB) configured to be electrically connected to the radiator. The radiator includes a first conductive pattern formed on a first surface in the stoke; a second conductive pattern formed on a second surface perpendicular to the first surface; and a connection portion configured to electrically connect the first conductive pattern and the PCB. The first conductive pattern and the connection portion may be configured to radiate signals in a first frequency band, and the first conductive pattern and the second conductive pattern may be configured to radiate signals in a second frequency band different from the first frequency band.
